Integrated Volatile Metabolome and Transcriptome Analysis Provides Insights into Floral Aroma Biosynthesis in Waterlilies (<i>Nymphaea</i> L.).

ABSTRACT: Waterlily (Nymphaea L.), a globally renowned aquatic ornamental plant, is prized for its aesthetic flowers and intense floral fragrance. However, the molecular mechanisms underlying floral scent biosynthesis in waterlily remain poorly characterized, and integrated analyses of dynamic volatile emission patterns and their associated biosynthetic pathways are lacking. In this study, we combined headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS) with transcriptome sequencing (RNA-seq) to investigate the composition, emission dynamics, and biosynthesis of volatile organic compounds (VOCs) in the stamens of Nymphaea 'Paul Stetson' across three developmental stages. A total of 671 VOCs, classified into 14 categories, were identified. Transcrip
